When the NFL draft kicks off at 8 p.m. today (ESPN, NFL Network, live blog), quarterbacks Jared Goff and Carson Wentz are expected to go first and second, to the Los Angeles Rams and Philadelphia Eagles, respectively.

Beyond that, things are murky, though two story lines could rule the night (and impact who’s available for the Detroit Lions with the 16th pick).

First is the case of Myles Jack.

Jack is considered one of the top handful of prospects in the draft, a do-it-all linebacker from UCLA who missed most of last season with a torn meniscus in his right knee.

That injury and its resulting degenerative condition raised concerns at the NFL’s combine medical recheck earlier this month, and it appears to be pushing him down draft boards across the league.
